Binding Content Of ContentPresenter

I am making a custom label

Border CornerRadius="10"  Background="#428bca" Height="{TemplateBinding Height}" Width="{TemplateBinding Width}">
        <ContentPresenter VerticalAlignment="Center" HorizontalAlignment="Center" >
            <TextBlock.Foreground>
                White
            </TextBlock.Foreground>
        </ContentPresenter>
    </Border>

I want to bind the content of ContentPresenter in such a way that ,when I change the length of the content , size(width and height) of border will get automatically adjust so that i don't have to change it manually.

The following Label should do what you want. Note that if it is a child of e.g. a Grid, you have to set the alignment properties to some other value that the default Stretch, because otherwise the Label will be resized by the Panel (for example to the size of the Grid cell that it occupies).

<Label Content="Hello, World."
       BorderBrush="Black"
       BorderThickness="2"
       HorizontalAlignment="Left"
       VerticalAlignment="Top">
    <Label.Template>
        <ControlTemplate TargetType="Label">
            <Border CornerRadius="10" Background="#428bca"
                    BorderBrush="{TemplateBinding BorderBrush}"
                    BorderThickness="{TemplateBinding BorderThickness}">
                <ContentPresenter Margin="{TemplateBinding Padding}"
                    Content="{TemplateBinding Content}"
                    ContentTemplate="{TemplateBinding ContentTemplate}"/>
            </Border>
        </ControlTemplate>
    </Label.Template>
</Label>

In order to reuse this ControlTemplate for all your Labels, you might put it in a default Label style:

<Style TargetType="Label">
    <Setter Property="HorizontalAlignment" Value="Left"/>
    <Setter Property="VerticalAlignment" Value="Top"/>
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="Label">
                <Border CornerRadius="10" Background="#428bca"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">
                    <ContentPresenter Margin="{TemplateBinding Padding}"
                        Content="{TemplateBinding Content}"
                        ContentTemplate="{TemplateBinding ContentTemplate}"/>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>
